Solution #6: Update the operating system

Android launches software update at least twice in a year. Your Galaxy S9 and S9 Plus should be updated to the latest software. System update fixes many petty issues and bugs in the phone. Moreover, it helps your phone run smoothly for a long time. Updates are introduced to remove old bugs, which were there in previous software. During software update, keep your phone connected to a power source as the process may take a long time and consume your phone’s battery.

Step #1. Open Settings on your Galaxy S9/S9 Plus.

Step #2. Tap on Software Update from options.

Step #3. Now, tap on Check for Updates.

Step #4. The device will start scanning process; then tap on Update Now to download the latest software version.

IMPORTANT: During software update, connect your phone to Wi-fi network and not to the mobile data as you might get a bill shock at the end of the month.

Solution #7: Check Third-Party Apps in Safe Mode

Some third-party apps (if not updated properly) can cause the issue of overheating. You can check such apps by running them in Safe Mode for a few minutes or hours.

If you don’t find any issue while Safe Mode is on, the third-party app is likely to cause some problems that result into overheating of your Galaxy S9. The problem apps never run in Safe Mode, and therefore, you need to take some action on those apps, which are the reasons why your Galaxy S9/S9 Plus is overheating. You can boot your phone into Safe Mode by following the steps given below.

Step #1. Press and hold the Power button on your Galaxy S9/S9 Plus until the Reboot to Safe Mode option appears on the screen.

Step #2. Tap on the option and wait for the device to restart.

Step #3. When your phone is in Safe Mode, you can keep it for a few hours or some days to check the results.

When you get to know that some third-party apps (or a single app) are creating the issue, you can take a decision to uninstall that app manually from the Safe Mode. Alternatively, you can remove those apps by doing Factory Reset.

Note: Normally, the procedure to boot Android devices into Safe Mode remains the same on all phones and tablets. Check our guide to enable or disable Safe Mode on Android Oreo 8.0 device.

Solution #8: Factory Reset your Phone

This you should do in the last resort as the action will remove all data from your device. It is advisable to take backup of your Galaxy S9 and S9 Plus before you go for Factory Reset.

Once you take backup of your device, follow this complete guide to factory reset your Samsung Galaxy S9 and S9 Plus.
